Answer:
The relationship is positive.
The model predicts a score of 60.
Not sure what part b is.
Step-by-step explanation:
Since while the money spent on advertising increases while the items sold increases, we have a positive relation between both variables.
By looking at where 30 is on the graph, we can see it lines up with 60,the middle between $40 and $80 on the y axis and so we know this is the cost associated with this value.
Answer:
The length of the angle bisector of angle ∠A is 6.01.
Step-by-step explanation:
It is given that length of leg AC = 5 ft and the hypotenuse AB = 13 ft.
Using pythagoras theorem








Bisector divides the angle in two equal parts, therefore,

In triangle ACD.





Therefore the length of the angle bisector of angle ∠A is 6.01.
Answer:
The equation is y = 10x + 6.
Step-by-step explanation:
In a slope-form equation, y = mx + b, m represents gradient and b is y-intercept. Given that slope is 10 and y-intercept is 6. So the equation will be y = 10x + 6.
